*Where to find official documentation*

The official documentation for CVS describes this in far more detail. This 
page is just a summary, and might not be adequate for what you are doing. 

The CVS documentation can be found using the "info cvs" command, and also 
online at http://www.gnu.org/manual/cvs/ 

*Creating multiple new CVS repositories*

To create the multiple repositories for two projects, "firstProject" and 
"secondProject", you would use a command like:
*: cvs -d /home/cvs/firstProject init
*: cvs -d /home/cvs/secondProject init

For more detail see 
{link: http://www.gnu.org/manual/cvs/html_chapter/cvs_5.html#SEC23 "Creating a repository"} in the CVS manual

*Importing files into the new CVS repositories*

Once these repositories are created, you can "import" any existing source 
files into the project using commands similar to:
*: cd ~/firstProject && cvs -d /home/cvs/firstProject import -m "Imported
sources" firstProject firstProject start
*: cd ~/secondProject && cvs -d /home/cvs/firstProject import -m "Imported
sources" secondProject secondProject start
